He is raising flop cbets a lot, but this deep I thought to have enough implied odds with the double gutshot to call.
On the turn, he can have set, flushdraw, but aggro enough to barrel, so I went for the chR. Only KQ is beating me, and he is capable of raising me with GS+2over, but his range is much wider than that.
What do you think?

Even though he raises a lot CBs I'd say that I'd still CB in those spots unless I really have a feeling that he raises a lot in those spots. We still have backdoor draws + of course double-gutter.

But the only problem here is that we can't continue after he raises being IP, we just don't get the implied odds to draw while also being OOP. You might even have reversed implied odds cause you can never be sure where we stand for example if we hit the T - he could easily have better straight. Which means I'd Bet/Fold the flop instead Bet/call. But otherwise not much to comment.
